What sets the Xperia models apart from other Windows devices is its interactive panel interface that gives you instant access to the apps you use most and can be customized to your lifestyle. The Xperia X2 comes preloaded with 14 panels and there are 16 others available for download, including those for Skype, CNN, and Google.
Sony Ericsson also added something called the SlideView feature that
notifies users to missed calls or new messages and provides quick
access to them.
The overall design of the Xperia X2 looks the same as its predecessor. It has a candy bar shape that slides open to reveal a full QWERTY keyboard. However, the X2 doesn't quite have the solid construction of the Xperia X1, and though it's lighter, it did feel a bit plasticky to us.
The Xperia X2 gets a huge bump in the camera department, going from 3.2 megapixels to 8.1 megapixels. The camera has up to 16x digital zoom, auto focus, image stabilization, geo-tagging, and video recording capabilities.
